How and in what order to adjust picture quality...

on different HT components?

Suppose you have a quality DVD player which has adjustments for Brightnes, Contrast, Color, Hue, Sharpness, etc. and if you have a projector and a scaler, these all of the above adjustments are available in these components too. So, which one do you adjust first? DVD player, Scaler or Projector and how do you do that? If you want to keep some of these components neutral and adjust mainly one component for the best picture, how do you know that the unadjusted components are neutral?
Ask your video questions here :
I second AVSFORUM.COM. Also, do a search for ISF certified technicians, etc. There's a website for getting all this info called something like or whatever. But if you do a search, you'll find it. I forgot the website.
good luck
